IMPROVEIVI ENT IN VEHICLE-.AXLES Specification forming part ofLettersPatent N0. 11,764, dated January 28, 1879; application iled December 16,1878.

To all whom 'it may concern:

Be it known that I, Louis A. lVIAYALL, of Philadelphia, Pennsylvania,have invented a new and useful Improvement in (Jarriage Axle Boxes, ot'which the ibllowing is a speciiicatiou:

The object of my invention is to combine the box of a carriage-wheel anda grooved axle-journal with retaining and releasing de vices,substantial] y as described hereinafter, so that the wheel can bereadily withdrawn from and as readily connected to the said axle.

In the accompanying drawings, Figure 1 is a longitudinal section ot' abox for carriagewheels, with devices for connecting the wheel to andfreeing` it from the axle; Fig. 2, a

transverse section on the line 1 2, Fig. l; and' Fig'. 3, a transversesection on the lille 3 4, rig. 1.

A represents a portion of the axle of a carriage or other vehicle, and Athe journal, adapted to the journal-box I3, which may be -Iitted andsecured to the hub of the wheel in the usual manner.

A hub or enlargement, b,'is formed on the boX, andin the face of thishub are cut radial guiding-slots L -three in the presentinstanee. Intoeach slot fits a projection, o, on one side of a slide, l), on theopposite side of which is another projection, f, adapted to one ofthecani-slots h in a plate, G.

The slides are adapted to a groove, my, in the axle, and are, with theplate ("r, confined to their places by a cap, 1I, which is screwed orotherwise secured to the enlargement b of the box B.

A set-screw, a, passes through the cap 1I and into the plate (l, so thatthe latter cannot be turned without the said cap.

The plate Ur has a collar, '5, to which is adapted a nut, J', thelatter, when it is Soren-"ed up, bearing` against a central enlargementof' the cover-plate ll, so as to act as a jam-nut.

As shown in the drawing', the slides project into the `eroovem ol" theaxle, thereby rea-ining, the box and wheel on the same. The wheel,however, is at liberty to turn on the axle, and cannot be withdrawntherefrom as long as the parts bear the relation to each other shown inFigs. 'l and 2.

When the wheel has to be detached from the axle, all that is necessar fis to irst loosen the nut J, and then turn the cap ll, and with it theplate Gr, until the cani-slots withdraw the slides from the eroove motthe axle, when the box will be at liberty and the wheel can bewithdrawn.

As long` as the screw n remains in its place the turning of the cap llon the hub will be limited by the movement of the slides; but-onremoving the screw the cap may be entirely detached from the hub ofthebox, and the operating parts may then be removed for cleansin orrepairs.

I claim as my invention- 1. rIhe combination ot' the groovcd axle A, thebox B and its slides l), the cap ll', and the plate G, having'cani-slots adapted to projections on the slides, all substantially asspecified.

2. The combination of the grooved axle A, the box I3, the slides I), theplate (l, the cap l-I, and the nut J, all as set forth.

In testil'nony whereof I have si gned inynalne t-o this speciiieation inthe presence of two subseribingwitnesses.

LOUIS A. MAYALL.
